Drug, gun arrests made in Lynn, Revere

Federal prosecutors say 15 men from Boston's North Shore area have been arrested on federal and state drug and firearms charges.

The U.S. Attorney's office said the men were arrested Friday morning, most in Lynn and Revere.

Nine have been charged in federal indictments on drug trafficking and weapons charges. Five were charged by the Suffolk District Attorney's office in Boston and one by the Essex District Attorney's office in Salem.

Prosecutors said the arrests were the result of a joint state and federal investigation on the North Shore.

Most of the charges relate to alleged trafficking in heroin and cocaine base.
